BENDING PRESS FOR TIE-PLATE FLANGES.

Application filed July 26,

My invention relates to improvements in presses for bending into jawforming relation the flanges of tie plate sections of the typecomprising a platform member having a perpendicular flange thereon knownin common usage as the Barrett tie plate and rail anchor.

An object of the invention resides in providing a press having aframestructure supporting a reciprocable ra'm carrying a punch block and infurther providing an anvil member with an inclined face having a diemember pivoted to said anvil in spaced relation thereto, adapted toco-operate with said punch block to bend the flanges of rail platesections thercover.

A still further object of the invention resides in providing a yoke orfreeing member pivoted at one end to said press frame and formed at itsother end with a bar having a shoulder thereon movable between said diemember and said anvil face, said shoulder being adapted to engage thelower end of a bent tie plate section and free the same fromengagen'ient with said die.

A still further object resides in providing hook members pivoted to saidram and adapted to engage the yoke or freeing member upon the upwardmovement of said ram so as to raise the same and cause the shoulderthereon to free the bent tie plate from the die.

A still further object consists in providing an inclined table arrangedin continuation with the face of the anvil, said table having a runwayformed therealong adapted to receive unbent tie plate sections and tofurther provide a slide operating along said runway for feeding theunbent tie plate sections upon said anvil.

A still further object consists in forming a cam on said slide adaptedto engage said hook and release said yoke and permit the shouldered barthereof to return to normal position. p

A feature of the invention resides in forming a shield on said slidealong the upper portion thereof so as to provide a trough adapted toreceive the unbent tie plates while the slide is being moved inwardlytowards the anvil, and to further provide a stripper adapted to operateupon tie plates so fed and to cause the same to fall 1n proper posi-1926; Serial N0. 124,847.

tion into-the runway when the slide is moved into normal position.

Vith the foregoing and other objects in dew, which will appear in thefollowing description, the invention resides in the novel combinationand arrangement of parts and in the details of construction hereinafterdescribed and claimed.

In the drawings:

Fig. 2 is a sectional elevational view taken on line 22 of Fig. 1.

Fig. 3 is an end elevational view similar to Fig. 1, the feedingmechanism being removed to illustrate the-die construction.

Fig. i is a' plan sectional view taken on line 4-4: of Fig. 3.

Fig. 5 is a perspective view of a completed tie plate and rail anchor.

My invention is adapted to operate upon tie plate sections which whenformed produce a tie plate and rail anchor such as shown in Fig. 5. of aplatform or body portion punched with suitable spike holes 11 and formedalong one edge with an outstanding flange 12 adapted to be bent over toform a jaw, constructed to receive the flange of a rail and securelyhold the same attached to the tie plate when said tie plate is spiked tothe tie. In the formation of said tie plate a rolled stock is used whichis formed with the flange 12 outstanding therefrom, which stock is cutoff in suitable lengths and punched with the spike holes. The tie platesections so formed are run through a furnace and the flanges thereofheated to a suflicient heat to enable the same to be readily bent wheninserted into the press. The heated tie sections are then fed into thepress forming my invention in which the flanges of the same are bentover to provide the construction shown in Fig. 5 and the tie plate soformed automatically re moved from thepress'.

The press on which the tie plate sections, as illustrated, are formed,consists primarily of a frame indicated in its entirety at A, whichcomprises a bed 13 and columns 14 and 15 issuing upwardly therefrom.These columns are formed with guide-ways 16 in These tie plates consistwhich is mounted a ram 17 adapted to reciprocate in vertical relation tothe bed 13.

Such structure being well known in the art the operating mechanism ofthe press has not been shown indelail. though it can read ily becomprehended that suitable operatiug inecl'ianisu'i may be employed forreciprotating the ram 17 in relation to the bed 13 and for tripping theram when required.

Upon the bed 13, which is formed with the usual. waste opening 18 shownin dotted lines'in Fig. 3, is mounted an anvil 19, which has attached toit a facing plate 20 having the face thereof arranged in inclinedrelation to the surface of the bed 13. Facing 20 is preferably arrangedat an angle of (30 with the surface of the bed 13 and is attached to theanvil 19 by means of screws 21. The anvil 19 is net integrally withabase 22 which rests upon the bed 13. Bolts 23 pass through the base 22and are adapted to be screwed into the bed 13 for firmly holding theanvil mounted thereon. To brace against the side thrust encountered inthe operation of the invention a backing block 2% is employed which issituated behind the anvil 19 and rests upon the base 22 and against theinner face of column 15. This backing block serves -to steady the anviland at the same time insures the accuracy of the machine in operatingupon the tie plate sections.

Along the lower portion of the anvil 19 is formed two depending arms orspaced lugs 25 which are bored to receive a transversely disposed shaft-26. These lugs and said shaft are disposed within the waste opening 18situated in the middle of the bed 13, though it an readily becomprehended that, if desired, the entire anvil structure may besutliciontly ele ated to bring the same above the face of the bed whenthe press is constructed with suflicient cl arance between the ram andthe bed. In conjunction with the anvil '19 I employ a mounting 27 whichis forn'ied with a depending ear 28 adapted to extend between the arms25 and to be pivoted upon the shaft 26. This mounting is formed alongthe upper portion thereof with a rabbet 2!) adapted to receive atool-steel formingaud spacing die 31 which is detacbably secured thereinby means of suitable bolts 80. It will be noted that the face of saidforming die is flush with the face of the mounting 27 and that the sameare so arranged as to lie parallel with the face of the anvil 19. Infeeding the tie plate sections to the machine, the same are fed with theout.- standing flange 12 thereof resting upon the upper edge of the diemember 31 as clearly shown in Fig. 3, the body of said tie plate beingpositioned between the said die member and the facing plate 20 of anvil19. it can readily be seen that upon movement of the mounting 27 towardthe anvil 19 that the tie plate section to be bent may be rigidlyclamped therebetween and so held as to permit the bending of the flangeabout the upper portion of the spacing die 2-31.

Directly attached to the rain 17, which is formed with a dove-tailedslot 32 for this purpose, is a punch block :3?) held in place withinsaid slot by means of a wedge 3 1. This punch block is formed with diefaces 35, 3t; and 37 conforming to the surface of the finished tie plateresting upon the anvil 19, the surface 37 engaging the extreme end ofthe flange 12 and bending the sameover the die member 31 as the ram 17descends in its guideways 16.

In bending the flange of the tie plate over the forming spacing die thesame is caused to tightly clamp about said die and to cling thereto,thus preventing the ready removal thereof. F or freeing the bent tieplate section from the die member 31, I employ a structure bestillustrated in Figs. 3 and 41. This structure consists of a yokeindicated in its entirety at B which consists of two spaced parallelarms 38 and 39 offset at 4:0 and 11. These arms are connected togetherat one end by means of a cross bar 12 and near their centers by means ofa brace43. The bar 12 extends outwardly beyond the otiset portion 10 ofarms 38 as indicated at l for a purpose to be pres ently described. Theextreme ends of the arms 38 and 39 are journalled to a shaft which ismounted in a bracket 16 secured to the outer portion of column 1% bymeans of bolts 17. Cotter pins -18 passing through the ends of the shaftl5 hold the same in proper relation to the yoke 13 so that the same mayfunction in the desired manner. it will be noted that the yoke 15 slopesdowuwardy toward the anvii 19, the bar 42 lying between the mounting 27and the anvil 19, said mounting and anvil being recessed at 19 and forthe reception of the same. The arms 38 and straddle the column ltwhilethe offset portions 10 and 11 thereof straddle the mounting 27, saidparts being arranged to permit the yoke to travel upwardly a su'flicientdistance to freethe bent rail section from the die .inember 31 as willpresently become ap parent. The bar 12 where it extends over the arms ofanvil 19 is formed of lesser depth than throughout the remainder of itsextent for the purpose of permitting the same to clear the upper portionthereof. Said bar 42 is further formed with. a shoul der 51 which liesimmediately beneath the lower edge of thebody portion 10 of the tieplate when the same is properly posi tion-ed as indicated. This shoulderis adapted to engage said edge of the tie plate and serves to free thesame from engagement with the forn' ing and spacing die 31- when Cirsaid yoke B is swung upwardly upon the shaft 45.

For operating the yoke B a shaft 52 is employed which extends directlythrough the head proper of the ram 17. This shaft has attached to it atits two extreme ends two depending hooks 53 and which are rigidlysecured to said shaft by means of keys 55 and clamp bolts 56. To holdsaid shaft 52 from longitudinal movement two collars 73 and 74; areemployed which are rigidly secured thereto by means of set screws 75.These hooks, at their lower extremities, are provided with catches 57adapted to engage beneath latch lugs 58 at tached to the yoke B. Theselatch lugs, which are preferably constructed of toolstecl, are mountedbetween forked protriv sions 59 formed on the offset portions 10 and 41of the yoke arms 38 and 39 and are held in place therebetween by meansof bolts 60. In operation the yoke B, through its own weight, dropsuntil the central portion of the yoke bar 42 engages the upper surfaceof the arms 25, the position of the same being illustrated in Fig. Uponthe ram 17 descending,'the punch block 33 operates to bend the flange ofthe tie plate as previously described and the hooks 23 descend alongwith said ram. hen the ram reaches its lowermost position, the catches57 on books 53 engage beneath the protruding portions of the latch lugs58, said yoke B being thereby caused to be swung upwardly as the ram 17ascends. During such upward movement of the ram 17, the shoulder 51 onthe bar 42 is caused to engage the lower edge of the body portion of theformed tie plate and to free the same from engagement with the spacingdie 31. lVhen the ram 17 reaches its uppermost position (Fig. 1), theyoke B holds the tie plate elevated and free from the spacing die 31.

For causing the catches 57 to engage the latch members 58 and to holdthe yoke B in elevated position, I employ the following construction,best shown in Figs. 1 and3. A lug 61 is formed on the hook memb'er 53and drilled to freely receive a bolt 62'passin'g upwardly therethrough.Bolt 62 isthread; ed into a bracket 63 attached to the ram 1.7 by meansof bolts 61-. Upon the bolt 62 is mounted a compression coil spring 65which is seated at one end against the lug 61 and at its other endagainst a nut 66 mounted upon said bolt. Lock nuts 67 and 68 hold thenut 66 and the bolt 62' in adjusted position. The spring65 yieldinglyholds the lug 61 against the head of bolt 62, thusnormally disposing thehooks 53 in the position shown in Fig. 3. As the ram 17 descends thecurved portions of the catches 57 and the latch lugs 58 contact causingthe hooks 53 to swing in opposition to the spring 65 until said catchesand latch lugs pass each other when saidhooks fall back to normalposition, engaging said latch lugs and causing the yoke B to be moved aspreviously described.

The mounting 27- and the die member 31 attached thereto are caused toclamp the tie plate by means of a bent lever 67 which is secured to saidmounting 27 by means of bolts 68. This lever extends outwardly to theside of the press and upwardly along the same where said leverterminates in an inclined portion 69 lying in proximity to the shaft 52andvadapted to be engaged by a sleeve 7 O mounted on said shaft, whenthe ram approaches its uppermost position. A coil spring 71 is attachedat one end to the extreme end of the inclined portion 69 of said leverand at its other end to a bolt 72 screwed into the guide member 16 ofcolumn 15. This spring acts to swing the mounting 27 and the die 31 uponthe shaft 26 and cause the same to move toward the facing plate 21 ofanvil 19 and rigidly clamp the tie plate mounted therebetween. Theinclined portion 69 of said lever is so constructed that when the sameis engaged by the sleeve 7 0 said lever is forced outwardly inopposition to the spring 71 to release the clamping action of saidmounting and facing die and to permit of the insertion of an unbent tieplate therebetween and after the removal of the bent tie plate. As willbe noted in Fig. 2,- thesleeve is situated between the hook 541 and thecollar 7 1 mounted on said shaft 52, so that the inclined portion 69 oflever 67 becomes guided between the hub of hook 54' and said collar 74:.By substituting sleeves of different diameters in place of the sleeve70, the opening of the spacing die and mounting can be adjusted at will.

The tie plate sections are fed into the machine as follows: Atthe sideof the press is arranged a table C which is positioned in inclinedrel'atioirand formed in continuation of the inclined face of anvil 19.This table is formed with lugs 77 by means of which the same may bebolted to the anvil 19 with cap screws 7 8, and is further formed with alug 79 permitting the attachment of the outboard end of said table to alog 60 independent of the framework A of the press. At the lower portionof table (I the same formed with an outstanding flange 81. 1). which hasattached to it a T flange spaced from and parallel to the surface ofsaid table to provide a groove or runway 83. Above this runway is formedanother groove 84. This groove communicates with a slot extending alongthe table C through a portion of the length thereof. A slide 66 of awidth equal substantially to that of the tie plate to be fed through themachine is slidably positioned upon the table C. Tl 1e lower portion ofsaid slide 86 rides within the runway 83, the upper portion thereofbeing formed with a T flange 87. which rides within the slot 84. Thisslide is held in position upon the table C by means of a.

screw 88 which passes through the slot and is screwed into the T flange87 thereof. A handle 89 is attached to the extreme end oi. the slice 8Gand extends along the same toward the inner end thereof, said handleserving as a means by which the slide may be manually recipro -atedalong the runway 83 and groove 8e.

Adjacent the anvil 19 I provide a chute 90 which leads up to and isconnected with the upper portion of the table C. This chute has sidewalls 91 and 92 and serves to convey the heated tie plates upon thetable C. As the tie plates are discharged from chute 90 the same slidedown table C until the lower edges of the body portion thereof becomelodged within the extreme end of the runway 83, as shown in dotted linesat .95 in Fig. 2. By now forcing the slide 86 inwardly the end 93thereoi is caused to engage the tie plate so positioned and to cause thesame to he slid along said runway and into the space between themounting, 27 and the anvil 19. The runway 88 is so situated in relationto the bar d2 of the yoke B that the bottom of the tie plate is alwayssituated above the shoulder 51 and so that the flange 12 ot the tieplate comes above the upper edge of the spacing-die 3. This permits thetie plate to be properly inserted between. the anvil and spacing die sothat the same may be operated upon as previously described. Where therehas been a previous tie plate bent in the machine, the edge of theincoming tie plate engages the edge of the bent tie plate and causes thelatter to be ejected from the machine, said unbent tie plate then takingthe position of the previous bent tie plate.

here a continuous run of: tie plates occurs provision has been made toautomatically hold back the following tie plates in. chute 90 while aparticular tie plate is being fed into the machine. This is accomplishedby providing a shield 9 1 which issues up wardly from the T flange 87 ofslide 86 and runs outwardly from the table C. When the slide 86 has beenslid inwardly this shield becomes positioned directly in trout ot thechute 90 so that the next following tie plate upon being" released bythe removal of the lowesttie plate will fall directly into the troughformed between said shield and the table C, where the same will he aslong as the slide remains in its inner position. Upon moving the slide86 outwardly to its position as shown in Fig. 2. the side wall 91 ofchute 90, which extends downwardly along table C, serves as a tripperand causes such tie plate to become disengaged from the trough formed byshield 94 and the flange 87 permitting the tie plate to drop noses r5into position in the runway 83 as soon a the slide has been completelywithdrawn. It will be hence readily comprehended that tie plates may besuccessively fed into the press by the manual reciprocation of slide 86so that the manual handling of the tie plates with tongs is eliminatedFor releasing the yoke B and permitting the same to return to normalposition, the handle 89 attached to slide 86 is formed with a cam 95best shown in Fig. l. This cam is situated. in proximity to thelowermost portion of hook 53 and is adapted to engage the same and throwsaid hook outwardly in opposition to spring; 65 so as to cause the catch57 to become disengaged from the latch lug 5S. Both the hoo s and 54:being keyed upon shaft 52 operate simultaneously and hence becomedisengaged from the latch lugs 58 at the same time. Cam 95 is designedto release yoke B as soon as the completed tie plate has been removedfrom the machine. This cam may be adjusted by means of a stud bolt 96which is secured at one end to the slide 86 and which passes through thehandle 89 near the cam member 95 thereon. Nuts 97 and 98 on said bolt oneach side of handle 89 are for the purpose of adjusting the cam 95 whichcoacts with the hook member 53. v

in summarizing, the operation of the marhine is as follows: The heatedtic plates are fed upon the table C by means of the trough 90 where thesame drop into the runway 83. By sliding the slide 86 inwardly thetor-ward edge thereof engages the tie plate and moves the same into thespace between the anvil l9 and the mounting 27, the dance of the tieplate resting upon the upper C(lfl't? oi the die member 31. [it the sametime a c ceeding tie plate drops into the trough, formed by the shield9st on table (l. where the same remains until the slide is ma uallyreturned to normal. position. During such return movement of the slide86. the side wall 91 oi. chute 90, serving as a stripper. holds thesucceeding tie plate baclr permitting the same to drop inplace in therunway 83 only when said slide has been fully retracted. Upon manuallyoperating! the tripping mechanism (not shown) of the press, the ram 17is caused to descend. As soon as the sleeve 70 on shaft- 52 leaves theinclined por tion 69 of lever 67, spring: 71 causes the mountiiur 27 andthe die plate 31 to securely clamp the body portion of the tie plateagainst the facing plate 20 ot anvil 19. When the punch block 33 strikesthe flange 12 of the tie plate, the same is bent over and upon theforming and spacing die 31 so as to provide the finished product. Thecatches 57 of hooks 53 and 54 slip beneath the latch lugs 58 when theram reaches its lowermost position. As the ram 17 ascends, catches 57engage the latch 1ugs58 and cause the f ll) lli) yoke B to rise,bringing the shoulder 51 of bar 42 in contact with the'lower ,edge ofthe body portion ofthe tie plate and freeing the same from the diemember31i As' the ram reaches its uppern'iost position sleeve engagesthe inclined portion 69 of lever 67 and withdraws the mounting :27 fromits clamping position upon the tiepla'tef The hooks 53 and 54 maintainthe yoke B in elevated position and consequently hold the tie plate freefrom the spacing die until the operator has had the opportunity tomanually shift the slide 86 and eject the bent tie plate from themachine and feed an unbent one into the same. As the bent tie plateleaves the machine cam engages the hook 53 and releases the yoke B whichagain resumes its normal position and completes the cycle of operationof the machine.

The advantages of my invention are manifest. 'lie plates maybeautomatically fed and ejected from ,the machine without the manualhandling of the same which in the case of heated structures is bothawkward and inconvenient. The machine may be made toifunction as rapidlyeras slowly as desired, and the same is so arranged as not to choke whenthe machine Lisstopped {for any purpose. The various operating elementsof the invention are readilyaccessible for inspection and repairs andmay be conveniently removed and replaced whenever the occasion requires.Those portionsof the device subject to greatest wear are formed oftool-steel or other suitable metal and may be removed and replaced asrequired. The

parts are so arrangedand constructed as to operate in a positiveandetlective manner so as to causethe machine to function withoutinterruption.
